The October 26, 2026 BloomTrading security incident affected 48 to 49 wallet addresses belonging to nine individual users.

Telegram trading bots like BloomTrading manage or hold user private keys to execute automated trades, creating central attack vectors for server-side vulnerabilities.

BloomTrading committed to fully reimbursing 100% of the stolen funds directly to newly generated, secure wallets designated by the nine affected users.

The reported loss figures from the October 26, 2026 BloomTrading exploit indicated an average price of approximately $101 per SOL during the drain.

The October 26, 2026 BloomTrading drain primarily targeted SOL holdings while leaving USD Coin (USDC) stablecoin balances untouched in affected wallets.

BloomTrading stated that no user private keys were compromised or accessed during the October 26, 2026 remote code execution exploit.

The single largest individual loss in the October 26, 2026 BloomTrading attack was 1,636 SOL, valued at approximately $166,000.

In September 2024, Telegram trading bot Banana Gun reported an exploit where 11 users lost approximately $3 million in Ether.

In October 2023, users of Telegram trading bots Maestro and Unibot lost a combined $1.1 million to smart contract router exploits.

BloomTrading temporarily paused platform services, took all systems offline as a precautionary measure, and instructed affected users to submit Discord support tickets.
